Cross-sectional asset pricing tests with GMM can generate spuriously high explanatory power for factor models when the moment conditions are specified such that they allow the estimated factor means to substantially deviate from the observed sample averages. In fact, by shifting the weights on...

We propose a novel Monte Carlo simulation method for two-dimensional stochastic differential equation (SDE) systems based on approximation through continuous-time Markov chains (CTMCs). Specifically, we propose an efficient simulation framework for asset prices under general stochastic local...

Adomain decomposition method is a powerful technique to solve nonlinear differential equations and nonlinear Integro - differential equations. This paper presents a novel way of computing Adomian polynomials for nonlinear terms occur in nonlinear differential equations through partial Bell...

The trajectories of particles moving in a real line and following the Geometrical Brownian motion have been studied. We take processes and give the generalization of the notions, descriptions and models of Geometrical Brownian motion with bouncing. Moreover, we derive the formulas, which enable...

We characterise the entire set of symmetric stationary Markov-perfect Nash equilibria (MPE) in a differential game of public good investment, using the canonical problem of climate change as an example. We provide a sufficient and necessary condition for MPE and show how the entire set of MPE is...

We investigate the empirical implications of the investment-based model of asset pricing for the Hansen-Jagannathan and Kozak-Nagel-Santosh discount factors in the linear span of equity returns. Our methodology is based on the equivalence between investment and equity returns implied by the...

In this paper, enlightened by the asymptotic expansion methodology developed by Li (2013b) and Li and Chen (2016), we propose a Taylor-type approximation for the transition densities of the stochastic differential equations (SDEs) driven by the gamma processes, a special type of Levy processes....

The application of random matrix theory made it possible to determine the place of Ukraine in separate clusters for certain groups of goods, as well as to find out the fact that Ukraine either operates within the general dynamics of the relevant market, or affects individual markets in some way...
